One Small Hero (1999)

Joey Cooper is a small boy who wants more than anything to be a member of the "Wilderness Club." But he has failed over and over again to pass the test and was not allowed to join. But when Joey gets home after his latest failure, he finds his mother has bought him all new camping equipment for his trip. Joey can't bring himself to tell her he didn't make the club so he takes the gear and leaves for the trip anyway, hiding on the bus. When a couple of kidnappers grab the kids, Joey is still in hiding and it's left for Joey to save them all.
